Alolan Marowak is only ever run in TR teams, if not it would suffer the same issue as Mega Camerupt: Lacking any speed to actually hit before getting killed. That's why Alolan Marowak runs 0 IVs in Speed and has a speed-decreasing nature. Swords Dance is mandatory for it to hit hard and act as a generic wallbreaker. Offensive typing is what makes it unique since it is capable of hitting every possible type for at least neutral damage, and access to Bonemerang means it can possible hit through substitutes.
